摘要： A proportional solenoid-controlled fluid valve assembly having a fluid pressure balancing arrangement includes a poppet and diaphragm. The valve assembly also includes a solenoid coil assembly having a cylindrical conduit and a magnetic orifice piece positioned within the conduit. A plunger is positioned within the conduit and is movable within the conduit between a de-actuated position and an actuated position. A valve poppet is provided having a top cylindrical upstanding portion and a poppet face configured to abut the valve seat. Further, a diaphragm is positioned within the valve base with the top cylindrical upstanding portion of the poppet extending through a diaphragm opening. A magnetic frame is also included for securing the valve assembly in an assembled configuration, wherein a magnetic path is formed by magnetic orifice piece, plunger and the magnetic frame and the solenoid coil is configured to be actuated such that the plunger moves towards the magnetic orifice piece, thus lifting the poppet and allowing pressurized media to pass from the inlet port to the outlet port.

摘要： A valve assembly comprised of a solenoid coil, having a coil bore, and being operative to produce a magnetic field when subject to an electric signal, a fixed magnetic pole piece within the coil bore, a generally cylindrically and axially translatable armature with a disc-shaped portion and an aperture therethrough, a valve base with a fixed portion over which the armature fits and forming a fluid cavity therebetween. The armature aperture allows a fluid to pass through the disc-shaped portion and into the fluid cavity to substantially equilibrate the fluid pressure on the armature in an axial direction. The valve assembly further includes a solenoid base which forms a chamber around the armature and a biasing mechanism between the magnetic pole piece and the armature which axially translates when the magnetic pole piece is subject to the electric signal, allowing the fluid to pass through the valve assembly in proportion to the electric current.

摘要： A proportional solenoid-driven valve control assembly comprised of a moveable, magnetic armature adjacent to a fixed magnetic pole piece, providing fluid leakage containment, and having no non-magnetic element for alignment, support, or magnetic flux path control. A valve unit coupled with the armature contains a fluid cavity in fluid communication with a fluid inlet port and a fluid exit port. The valve is closed by a poppet coupled to the armature. To compensate for fluid pressures exerted against the poppet, a flow restriction is provided between an armature cavity and the fluid cavity. In addition, a bore is formed through the armature to provide fluid communication between the fluid exit port and the armature cavity. This serves to balance fluid pressures at the fluid inlet and exit ports applied to the opposite sides of the fluid flow restriction.

摘要： A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed magnetic pole piece. The magnetic pole piece has a longitudinal axial pole piece portion, and a relatively thin, annular axial pole piece portion, that rapidly saturates, and is effectively mechanically solid with the longitudinal pole piece portion for fluid leakage containment. A radial portion is solid with the annular axial portion and provides support and alignment for the armature relative to the magnetic pole piece, without the need for non-magnetic material for alignment, support or magnetic flux flow path control.

摘要： A rectilinear motion proportional solenoid assembly includes a cylindrical housing containing an electromagnetic coil having a longitudinal coaxial bore. The housing contains magnetic material for providing a flux path for the magnetic field produced by the coil. A generally cylindrical magnetic pole piece element is inserted into the bore and a movable armature assembly of magnetic material is supported within the bore for movement along the longitudinal axis of the coil by a pair of thin, flexible suspension springs. One of the springs is located within the bore adjacent to one end of the magnetic pole piece whereat an axial gap between the pole piece and the armature is formed. A second spring is located within the housing within the vicinity of a radial air gap between the armature and the housing. The pole piece contains an auxiliary region adjacent to the axial air gap for shunting a portion of the axially directed magnetic flux, for effectively causing the force imparted to the movable armature by the application of a current to the electromagnetic coil to be substantially constant irrespective of the magnitude of the axial gap for a variation in the axial gap over a prescribed range.
